AUTOMATIC SHUTTLE-CONTROL MECHANISM FOR ADDING MACHINES.

Application filed July 28, 1923.

The object of this improvement is to provide means for automatically controlling the movement of the shuttle paper carriage at the will of the operator so as to greatly widen the field of use of this feature.

' In the customary arrangement of shuttle carriage mechanisms, the carriage usually shuttles from one side to the other after each handle pull, and therefore lists two columns. lVhe'n itemsare listed in one of the columns the paper does not space, thus causing items in the two columns to print directly opposite'each other. The mechanism is also usually arranged to non-add in one column and to add in, the other, thereby greatly simplifying the work of listing car number and amounts, voucher number and amounts, dates and amounts or any similar work where'one column s'hould add and the other merely designate.

This shuttling of the carriage usually continues on every stroke of the handle 'until the operator disables the mechanism by manual movement of a control'button. But, with this improved device, the shuttle mechanism is automatically disabled at the will of the operator and fonr'colurnns of work may be listed with a carriage that only shuttles in two positions, that is, which shuttles first to the ri ht where two columns of work are entere andthenshuttles to the left where twoniore columns are listed, all four columns being entered on a single line. The ,two columns on the left-would ordinarily be non-added and the two on the right would add. With this device the operator can also list a single column when the carriage is to the right and it will then immediately shuttle to the left and not space the paper, and then another column can be entered and the carriage will not shuttle or not space, but when the next or third item is entered the car riage will shuttle and will space, thus caus le line, the first of which would not add and would therefore be a designating number, while the numbers in the second and third columns would add.

Two columns may also be listed while the carriage is to the right, which would not Serial No. 654,453.

add, and one column may then be listed after the carriage shuttles to the left, which would add and which would allow the carriage to shuttle to the right again and to space.

This automatic shuttle disabling mechanism may be. set by the operator so that the carriage will shuttle and list only two columns in the usual way or both this'mechanism and the shuttle mechanism may he normalized and the machine used for straight adding machine work like any ordinary machine.

The accompanying drawings illustrate the device applied to a Dalton adding machine, although, it is obvious that its use is not restricted to this particular make of machine.

No attempt will be ma de to' describe in detail the operation ofthe Dalton. shuttle carriage machine, as the machine is' well understood by those skilled in' theart and is described in detail in Patent Number 1,582,830, issued Apr. 27, 1926.

The machine as a whole comprisesa base 10 and side walls 11 provided withinturned front flanges 12 and rear flanges 1,3. 'The main operating shaft 14 occupies the usual position near the base of the machinearid is provided with a fixedly mounted segment 15 which rocks with the main shaft under the pull of the operating handle and imparts the power for shuttling the carriage 16 which carries the paper platen 17 :and is mounted to ride back and forth along the double trackway 18, which features are of the usual type and do not require special description. The segment 15 has pivoted thereto a link 18, the upper end of which is pivoted to a bell crank lever 19 pivoted at its elbow to a stud 20 secured to the left side wall of the machine.

Theupper arm ofj'the bell' c'rank 'lever s provided with a stud 21 which is ada ted to engage the recessed end 220i 2. rive latbh' 23,which is 'mourited at stem end on a head'ed stud'24' carriedby-a slide bar 25 provided with front and rear slots 26 and 27, which s'lidably "engage with headed studs 28 and 29 respectively, which afford guides for the back and'forth movements of the slide bar. It is evident that when the drive lat'ch'23 is lowered, it will engage with the studc2lon the bell crank 19, so that with each forward movement of the operating shaft, a rearward thrust will be imparted to the drive-latch and thence tothe slide'.bar.

Theslide bar at its rear end has depending therefrom a bifurcated plate 30 which engages a roller 31 mounted upon an arm 32:. pivotedzat itscenter upon a -]ournal post 33, which 'loosely,journals a. ratchet wheel 34 provided with teeth 35 adapted to be engaged by .the end of a dog 36 which is "i'vote'd' to the'en'd "of the arm' 32 and held ienga emntwith the ratchet teeth by the laction oi a spring 37 connecting the do maarm' respectively. Each reciproca- 'tion offthe slide bar-w'ill feed-the ratchet "Theratch'et whee'Fis rigid with a. spur wheel .38 which meshes'with a pinion 39 on 'tl'ie'lower end of a'vertical shaft40 which isjournaled through'a jlower b'ra'cket' tl and an upper 'bracl'ret 42. "Thevertical .shaft at- -its upper-end carries adislr 43 which mounts 'a' pivot =stud- 45,'the' outer end of which is pivoted to a 'shuttle "arm"'46,"'the;rear endof which is pivotedto a rear'flange"47,'and the-forward 'en'dof which engagesanotch'AS in a tubular bar: 49, which'har forms. a transversely .ex- 'tenfding'fportion of. the -carriagestructure. antenna-of mechanisms above de i-sci'ibd in"engagement, each complete re- "ciprocatiOn of, the operating shaft-will cause "aShiittling'Qf the carriage first to the right and then .to' the left.

"The mechanism 'now' to be described is *de'signedfto disable the normal shuttling 5g eration'in conformity-with the principles 6 "the present invention.

Y A'nor'maliz'ing -lcnobfitl, within convenient r'each of 'the operator, is mounted upon the lower arm"51:of a bell'crank' lever52, which is pivoted -at 'its'elbow to a stud53 carried plate 54, secured to the'front wall of and the upper arm of the bell cranlr lever is provided with a rearwardlv turned tongue 55 which is'positioned to en- .gage a tongue56 on the forward end of a lever 57 which is fulcrumed on a shaft 58.

T44to which is pivotda link P The rear end 59 of the lever bears against a pin 60 laterally rojecting from the drive latch 23, so that when the normalizing knob 50 is drawn to the right, (see Fi 5) the forward end of the lever'57 will be epressed which lifts the rear end of said'lever and with it the drive latch 23, thereby disengaging the notch in the drive='latch'f-rom=t-he stud 21,- so that't-he latter mayrmove rearivardly as the main shaft is operated without impar ng-arearward t-hr-ustto the drive latch and the slide bar to which the drive latch is connected. This, of course, will have the effect of disabling the-shuttling mechanism and preventing transverse movement of the paper carriage.

The normalizing mechanism above described is for the purpose of completely disablingthe shuttling mechanism, but the mechanism now to be described isfor'the purpose of controlling the'shuttlingpfthe carriage in conformity with the; movements of the traveling stop carriage,"in whibh'the stops are set upby the actuation ofthe'numeral keys, so that a depression of a predetermined number of numeral"key s, as for instance seven, will automatically have "the effect of breaking the chain 6f 'mehhanisms which causethepa er 'carriage"to shuttle when the handle is pulled.

The stopv carriage isnot illustrated for the reasOri that it 'isof the we'll'known'lt ype, but the stop carriage "is" associated with "an escapement segment 61 whic-hiis'carried'fon the shaft-162 and swings'in a horizontal plane step by step as the'stop carriage is advanced from order to order. The escap'ementseg merit has secured theretoi'a cam seginenttli-l terminating in a' sloping shoulder 64, which cam segment ri les'again'st archer-"65' -carriedby a slide "l'ate 66 which is normally drawn to 't-he'rear'hy the action b'fza' spring 67 which servesto hold the roller65 in contact with the edge of the'can'i segment. As the stop carriage. (not shbwn) I advances by step' towards the left under the'actuation of the numeral' keys, the 'esc'apeme'nt seg- :inent and associatedcam segment will move in a clockwise direction,-'and"after' a 'prdetermined number of movements, the cam shoulder 64, ridi'n p'ast' the'roli'er 65;will permit 'a' rearwar movementof the slide plate 66, unless such movementis-I'irevented by mechanism: presently to'be described;

The slide plate66 i slotted-' toreceive the lower end of a bell cranklever 68 which is pivoted at its elbow to an upstanding bracket 69, and the upper-arm of the 'b ell crank lever carries a'headed stud TO-which engages with a slot 71 in a link 72, the upper end of which is pivoted to a for\varclly-ex-- tending tongue 73 forming a portion of a swinging bracket 7-1 which is mounted-upon the shaft'58. The swin ing bracket-'74 also is provided with a depending finger 75 which bears against a stud 76 on an arm 77 which depends from the lever 57 which controls the raising and lowering of the drive latch 23. With this arrangement, a downward movement of the link 72, which automatically takes place after the depression of a predetermined number of numeral keys, will cause a lifting of the drive latch and a disengagement of the shuttling mechanism, so

that the latter will remain idle during the operation of the main shaft.

In the above circumstances, it is necessary to provide means for disabling the normal operation of the line spacing mechanism. Such disabling means comprise a block arm 78 which forms a constituent part of the swinging bracket and extends rearwardly therefrom into close proximity with the lower end of a carriage-space drive arm 79 mounted upon a shaft 80 which controls the operation of the line spacing mechanisms which impart rotation to the paper platen. When the swinging bracket is actuated in the manner stated the block arm 78 will be lifted into the position shown in Fig. 3, where it will block the advance of the drive arm 79, so that the line spacing mechanism will fail-to function.

The automatic mechanism actuated by the slide plate 66 to prevent further shuttling maybe disabled by the movement of a control. lever 81 projecting from the forward portion of the machine through a slot 82 in a plate 83, best shown in Fig. 6. With the control lever in position marked S, the connections will be automatically disabled after the depression of a given number of keys, but if the lever is drawn downwardly to the position marked N and held in the notch 84, the automatic mechanism will be disabled by the action of a draw rod 85 provided with a finger 86 at its rear end, which finger co-acts with a finger: 87 on the forward end of the slideplate 66, so that whenthe control lever 81 is drawn down it will, through the action of an arm 88 imparta forward movement to the draw rod 85 thereby bringing the fingers 86 and 87 into engagement, so that the slide plate 66 will be locked against rearward movement irrespective of the positioning of the cam segment 63, so that shuttling will take place upon every pull of the handle even though the maximum number of number keys have been depressed.

From the foregoing description, it will readily be understood that work such as shown, for example, in Fig. 4, may be produced, in which work the two left hand columns contain designating numbers and the two right hand columns contain numbers to be added. To perform an operation of the character indicated, the normalizing knob 50 is set to the left in Fig. 5 and the automatic shuttle control lever 81 is set at S as in Fig. 6. The paper carriage should first be moved to the right or non-add position bringing the left hand column of the paper to the printing line, whereupon the item 510 is entered and followed by seven ciphers, thus, 0000000. 'lhcse ciphers may be entered with the cipher key.

The entering of the ciphers has the effect of moving the escapement and cam segments sufliciently to disengage the shuttling mechanism and block the line spacing mechanism, and as the handle is operated, the item 510 will print, since a split is provided for cutting out the seven ciphers to the ri ht. The introduction of the seven ciphers t en has the effect of setting the stop carriage into the left adding section, so that the designating item 510 will be printed in the extreme left column, and with the paper carriage shuttled to the right, the adding mechanisms will be thrown out of commission, through the functioning of mechanism, which forms no part of the present invention, so that the items will be merely listed and not added.

The movement of the handle, although it does not shuttle the paper carriage, has the effect of restoring the stop carriage to the right hand position as is the customary practice, so that the operator is now ready to set up the second column of items beginning with number 215 in the example shown. After setting up this item, the paper carriage, still remaining in the right hand position, will prevent adding, but, in this instance, no .ciphers are introduced, so that the printing will be effected by the printing mechanism provided for the lower orders, and the-item will be entered in a column to the right of the column previously printed.

Since only three numeral keys were depressed in setting up the item in the second column, the top carriage escapement will not have traveled far enough to disable the shuttling mechanism, so that, in this instance, when the handle is pulled, the carriage will be shuttled tonthe left or into the position in which the adding mechanism is actuated. The operator, in the example shown, then sets up the item 6357 followed by seven ciphers, which, as before, has the effect of setting upthe stop carriage into the left adding section and of disabling the shuttling mechanism, so that on the pull of the handle the item in the thirdcolumn will be printed at the proper column position and added into the accumulating wheels (not shown) in theusual manner. The stop carria e having been restored to its normal rig 1t hand position, the operator is now ready to set up the last item in the extreme right hand column and since no ciphers are added to this item, the carriage will shuttle in the opposite direction.

With the paper carriage in the right hand position for setting up the two non-add columns, the line -spacing mechanism will be blocked'asthe carriage is shuttled by the liftingof' the block =arm.78 into position to engage the roller on the end of the line spacing-arm-79,Ihut when the paper carriage has been shuttled over into the-left hand position, the block arm and line spacing arm will occupy positions out of register -with one another, so that the-lifting of the block arm w-ill-be ineffective to prevent a full movement of the line spacing arm. This being the relationof the qiarts, it follows that when6357 -is setup fol owed by seven ciphers and the-handle has-been pulled, the shuttling mechanism is disabled and the block anm' li-fted into position to prevent line spacing,--but-after the settingup of the fourth itom -el425-which is not followed by chipers, the=o erat-ion of the handle will allow both shu ing-and line spacing; so that the paperplaten-will-a'gain move to the right position with the paper properly spaced to receive the next horizontal row of figures.

Isn=the example shown, a thirteen column machine-is-used, two left hand columns being entered with the non-add'parts effective to prevent adding while the two'right hand columns are listed-21ndaccumulated at the same time, there being a split in the-adding section to permit such double-accumulation.

=By entering items into. the stop carriage and bythrowing these items into a position where-the -.automatic control parts will or will-not be'efie'ctive, it is possible at the will of the operatortoeither list two non-add columnsz-and-oneiadd column orto-list one nomadd column'and two add columns, or by setting-the-automatic control lever 81 at the point N it is'possible'to l-ist'a single nonudd column -a-nd:-asingles add column, both of-which have .a-c'apacity: of thirteen digits. Also armovin-g of the control .knob 50 to the ri ht hand position-will have the effect of 1-i-- in'g theldrive latch and disabling the sliutthng mechanism, and this inconjunction with a movement of the-control lever to the notch 'N will prevent -a blocking of the linespacing mechanism, so that with the control-members thus adjusted, all of the special "features of -the present invention will be thrown out of commission and the machine may be used as an ordinary adding machine.

The invention is one which suitably combines withmn adding machine-of well known standard type without in any way impairing the-adding functions or capacities of the machine,- and without necessitating any substantial change or-modificat-ion 0 standard equipment and withoutincreasing the bulk of the machine.
